WALL-ERECTING APPARATUS.

Specification of Letters Patent.

Patented Au o, rare.

Application filed August 12, 1910. Serial No. 576,820;

To all whom it may concern:

Be it known that I, HILDER DAw, of the' city of Montreal, in theProvince of Quebecv and Dominion of Canada, have invented certain new and useful Improvements 1n Wall-Erecting Apparatus; and I do hereby declare that the following is a full, clear, and

exact description of the same.

This invention relates particularly to an apparatus for forming and supporting a,'

mold to be used in the construction ofoconcrete walls or the'like.

The object of my invention is to provide a mold for concrete walls or the like, which may be readily dismembered, shifted and reerec ed to continue the wall in a horizontal direction, after the completion of which it may be returned to its former position to allow the wall to be heightened; to provide displaceable spacing means for certain of the members of the mold structure, such structural member being held by the concrete during erection of the wall and the removal of the spacing means after the concrete has set permitting such structural members to be removed; to provide readily adjustable int-ans for preventing the corners of the mold from spreading; and to improve the general construction of apparatus of this -yp My invention'consists of the particular construction, arrangement and combination ofparts hereinafter described and pointed out in the claims. For full comprehension, however of my invention reference must be had to the accompanying drawings forming a part of this specification, in-which similar reference characters indicate the same parts and wherein Figure l is a perspective view illustrating my improvedapparatusy Fig. 2 is a plan view partly in section of a corner thereof illustrating particularly the means for rein forcing the corner; Fig. 3 is a vertical sectional view taken on line A A Fig.2; Fig. 4 is a detail perspective view'of the means for reinforcing the corners of the apparatus; Fig. 5 is a similar view of the spacing means; Fig. 6 illustrates one of the bed plates in perspective view; Fig. 7 is a detail perspective view of a coupling forming a part of my invent-ion; and Fig. 8 is an elevation of the means for securing in place the reinforcing means illustrated in Fig. 4.

My improved apparatusis supported on structural members comprising a series of bed plates b placed on the ground at suitable distances apart, transversely to the wall about to be constructed. Secured to each of the bed plates near the opposite ends thereof, are two vertical standards 0 and d respectively composed of suitable lengths of 'T-iron disposed with their webs c facing in opposite directions; these standards having feet e formed by cutting olf the lower ends of the webs and bending the flanges thereof, the bent portions being braced by angular braces f riveted to the standards.

These feet serve as a means of attaching the standards to the bed plates to which latter they are secured'by bolts 9 passing there through and through the braces f and screwed into the tapped holes h in the bed plates. The ends of the bed plates to which the standards d are secured being preferably provided with a series of the tapped holes h to permit of the standard being spaced apart varying distances from the standard 0 to provide for different thicknesses of walls.

The adjustable standards are each supported by a pair of T-iron struts k and Z (composed of T-iron) the webs thereof being perforated at one end; these struts are secured one above the other to the webs c by means of square headed bolts m which pass through the perforated ends of the struts and engage in holes .0 located atintervals along the length of the web, where they are secured by nuts 0 the heads n of the bolts on being large enough to engage the flange of the standard to hold the bolt against rotation while the nuts 0 are being screwed thereon. The struts 7c and Z extend diagonally downward from the standard to the ground, the upper strut k being necessarily of greater length than the lower strut Z. The lower ends of such struts are curved such curved ends secured thereto by clamps downwardly as at p and bear with such.

' a each consisting of a member 3 of U-form,

one end of which is reduced and inserted through a connecting link and bent to form an eye 6 pivotally securing the link' 4 thereto. The U-member straddles the anchor pin q'and the curved end of the strutwhile the connecting link extends across the underside of the latter, the oppositeend 4 of the U- member being inserted through the connecting link, such last mentioned end being screw-threaded and adapted to receive a nut. 8 which is screwed against the connecting link 4: thus tightening the clamp. The upper ends of the struts are slightly curved and have the flange 9 thereof turned down as at r to clear the webs c of the standards.

The standards 0 and d are connected together near their upper ends, and the relative distance therebetween maintained, by rods 8 screw-threaded at their opposite ends. Each of "these rods has a sleeve 25 passed thereover leaving the screw-threaded ends exposed which are inserted through the flanges of the standards, the rods being held in place by nuts a which bear against the outer faces of such flanges, theop osite ends of the sleeves engaging the inner aces thereof and acting as distance pieces for the standards, the height of. such sleeves being detlermined by the desired thickness of the wa ls.

The above described framework being I completed, boards 0 are then set on edge flat against the standards and built up to.

the required height thus presenting a space which constitutes the mold now in readlnessto receive the concrete .10. To permit of the ready .removal of the bed plates when desired, they have placed over them removable spacing blocks'll and '12 of a size equal,

to theexposed surface of the bed plates on which latter the blocks are placed, such blocks being-each composed of a pair ofoppositely facing wedge-blocks placed with,

their inclined facesin contact as illustrated in Fig. 1. blocks in such a manner they can be easily removed as the lower block does not contact with. the concrete either on its top or botangle thereto and to prevent the tendency of such boards to spread apart at this connecting point and so cause the corner to be roughly formed, an angle iron having one flange a: of greater length than the other flange y, is placed vertically over this cor ner and arranged to have the longer flange extend over the exposed ends of the boards forming the outer wall of the mold for one By constructing the covering side of the corner andoverlapthe ends of the boards abutting thereagainsta The angle iron is held in place. by means of a. chain? sides of the webs and serve to tlghten the chain 2. I

By my improved construction the same structure may be utilized'in. the construction of a horizontal continuation of the wall as was used for the original portion as follows ':When the concrete has become sufiiciently hardened to' dispense with a .support the struts is and l are first disconnected from the standards by removing the bolts m and the clamfps 3, the standards being then disengaged om the bed plate 6 by re moving the bolts 9 and the, boards '0 are then removed leaving the bed plates b. and the anchor pins 9 undisturbed. The boards a, standards 0 and d and str ts k and l are then again erected as above escribed in the position necessary for the continuation of the wall thus doing away withthe necessity of providing at one time a structure for the complete wall. F

When it is desired to heighten the wall and the concrete has hardened sufficiently to support such extension the boards, standards and struts are placed in their original having been left in place, so that when the When it is desired to'build a wall having battened sides the standards (1 are given the desired inclination, the series of holes 0 before mentioned, permitting the struts to be secured to the standardswith the latter having different angles of inclination.

What I claim is as follows 1. In a wall erecting apparatus, the combination of a pair of standards, a bed plate securing said standards together, and a pair of readily removable spacer blocks of wedge form placed over said bed plate to permit of the removal of the latterafter completion of the wall.

2. In a wall erecting apparatus, the combination of a bed plate, a pair of members resting on the bed plate and spaced apart to form the sides of a mold to receive the material composing the wall, and a pair of oppositely arranged wedge shaped spacing blocks placed upon said bed plate.

3. In a wall erecting apparatus, the combination with a pair of angularlydispos'ed and abutting members forming the outer sides of a mold for a wall corner, and an angle strip placed over such members at a point where they form the corner, of. a chain I'Wall is completed there is no unevenness'on the surface of the wall.
